ImPro MX-9 DSP Karaoke Mixer & Digital Echo Processor – Bluetooth, FBX Feedback Suppression, 4 Mic Inputs, Optical & AUX Music Inputs

Bring the "karaoke room" sound home (or clean up a small venue) with the ImPro MX-9 - a 1U rackmount DSP karaoke mixer + digital echo processor built for vocals. You get the controls that matter most to singers: rich echo, smooth reverb, and FBX feedback suppression, plus flexible music inputs like Bluetooth and Optical (TOSLINK) for easy TV / karaoke player setups.

Why singers love the MX-9

Big vocals without the squeal.
The MX-9 is tuned for karaoke-style vocal processing: dial in Echo (Level/Delay/Repeat) and Reverb (Level/Delay/Pre-Delay) to get that "finished" vocal sound, while FBX helps reduce the harsh feedback that can happen when the room gets loud.

Key Features:

• DSP Vocal Effects: Digital echo + reverb controls for a polished karaoke vocal
• FBX Feedback Suppression: Helps reduce feedback/whistling in live setups
• 4 Mic Inputs: Connect up to four microphones (2 front + 2 rear)
• Mic & Music Tone Shaping: Tone controls for clearer vocals and better music balance
• Bluetooth Music Streaming: Play backing tracks wirelessly from your phone/tablet
• Optical + AUX Music Inputs: Easy connection to TVs, karaoke players, and media devices
• USB Port: For compatible USB media playback (device/format dependent)
• Line Outputs for System Integration: Main L/R + Center + Sub outputs (XLR and RCA)

Simple Setup:

1. Connect your TV / karaoke player to the MX-9 using Optical or AUX (RCA).
2. Plug microphones into Mic 1-4.
3. Send the MX-9 outputs to your power amplifier or powered speakers.
4. Add Echo/Reverb to taste, enable FBX if feedback appears, and you're ready.
